My new (to me) Felt 29er has Recon Gold solo-air forks which are vile* compared to various other RS forks on my other bikes.

I also have some 426 Revs in 26″ flavour going spare, with dual air and MoCo.

So, is it possible to create a Frankenfork, with the Revs internals in the Recons stanchions and lowers?

*A winning combo of no small bump compliance and bottoming out.

probably yes

The only part that will work is the MoCo. Stanchions, lowers, air assembly will not be compatible.
You say ‘New to you’. I presume its second hand bike then. Those forks prob just need a service as its prob little more than moisture and dirt in the lowers making them feel rubbish.
