The outgoing longwave radiation is composed not just of the radiation that leaks through to the top from the warm lower layers, but also of the «cold» radiation emitted from the upper atmosphere.
Surface is warming but the upper atmosphere is cooling equally to surface warming, and there is no energy imbalance.
Lower Atmosphere is warming, oceans upper layers are warming, arctic summer sea ice is disappearing, WAIS and Greenland are both losing mass annually and the majority of the earths glaciers are losing mass too.
Thus, adding absorption to some new band will initially tend to warm the colder upper atmosphere and radiatively cool the lower atmosphere and warm the surface (The forcing at any level will be positive, so the surface + troposphere will warm; if some of the increased flux escaping in parts of the spectrum where the abover layers have sufficiently small optical thickness, some of the upper - level cooling will persist.
Less TOA cooling will occur if bands are placed where, in the upper atmosphere or near TOA, they absorb more of the increases in radiation from below from surface + tropospheric (+ lower stratospheric) warming.

As we know from laboratory experiments, mathematical calculations, and observations of Venus and other planets in the Solar System, greenhouse gases change things in two ways: they trap heat from the sun in the lower atmosphere, thus making the surface of the planet warmer; and they keep heat from rising, thus making the upper atmosphere colder.
- temperature sensors on satellites report much less warming in the upper atmosphere (which the theory of global warming predicts should warm first) than is reported by temperature sensors on the ground.
Add in that if it's the sun, the entire atmosphere will warm, since there's just simply more energy put in to the system, whereas if it is CO2 or other blanketing method, there's no extra energy put in, therefore the ground will warm and the upper air cool (since the upper air isn't getting the warming from the lower layers it used to get and the lower layers aren't losing the heat they used to).
With no ozone, the atmospheric temperature would decrease monotonically, and we would instead have to speak of cooling of the «upper atmosphere» in conjunction with the surface warming due to increasing GHGs.

This would actually not be true at sufficiently high latitudes in the winter hemisphere, except that some circulation in the upper atmosphere is driven by kinetic energy generated within the troposphere (small amount of energy involved) which, so far as I know, doesn't result in much of a global time average non-radiative energy flux above the tropopause, but it does have important regional effects, and the result is that the top of the stratosphere is warmer than the tropopause at all latitudes in all seasons so far as I know.
The lack of ozone is chilling the middle and upper atmosphere, altering wind patterns in a way that keeps comparatively warm air from reaching the surface.

We can divide the atmosphere into a lower part (LP), which includes the surface and is the source of IR, and an upper part (UP), which we are asked to assume will cool when CO2 increases, in conjunction with the expected warming of LP from the enhanced greenhouse effect.
As more optical thickness is added to a «new» band, it will gain greater control over the temperature profile, but eventually, the equilibrium for that band will shift towards a cold enough upper atmosphere and warm enough lower atmosphere and surface, such that farther increases will cool the upper atmosphere or just that portion near TOA while warming the lower atmosphere and surface — until the optical thickness is so large (relative to other bands) that the band loses influence (except at TOA) and has little farther effect (except at TOA).
