While it did have some weapons capability, exploring the possibilities of COIN and CAS with the L-29 would be intriguing.
It was a quite robust design, so seeing the L-29 reworked to that job similar to how the T-37 was reworked to the A-37 is not unimaginable.
You could also take that a bit further if you combined the failed single seat aerobatics variant with the L-29 which had the sensor and reccon pallet. between the freed up space in what was the rear cockpit and the sensor pallet, there should certainly be the room to accommodate a laser designator in the front end of the pallet.
Single seat variant:
L-29R with Pallet:
As you can see, making the single seat version would not involve much more than painting over the rear canopy section and maybe making an internal bulkhead.
Maybe stick a bit more powerful engine into her and a couple of extra pylons under the wings and you'll have an eastern Dragonfly counterpart.
