What Solid State Amplifier can I build to suit my needs?

Hey all! I'm building a solid state amplifier with the main goal of live shows (in basements mostly). The primary speaker its driving is a Celestion G12T 75 along with a couple other smaller ones wound to get a final 4 ohm load.

My initial plan was to put something together really quick because I am in a time crunch. Particularly using a TDA7498 power amplifier as the final stage. I was planning on splitting my cabinet into 2 and running 2 separate lines to get a stereo sound. If this is a possibility I would like to build a stereo pre-amp stage. Something that has a lot of tone customization. I was thinking of even including an interchangeable tone stack (Fender/James). For a possible pre-amp stage I was thinking of using a Model Fet))) pedal design but I have doubts on how the voltage output of that would match the TDA7498.

Honestly I am down to scrap the TDA7498 if it means I can get something louder more suited for live shows.

Another idea I had was to run the signal through a common pre-amp stage then have a fx out channel which splits the signal into 2 to get a more stereo sound before going into the TDA7498.

Any ideas?
