3 in 1 firmware tft35

[madmonkey630]

Good morning all
above all, I'm not a programmer or developer or anything. I come here especially to know if my project is viable and if some of you could help me make it happen.

I come to the facts I am busy building a 3 in 1 3d printer (double extruder printer; laser cutter; wood engraver).
It is composed of a skr 1.3 tmc2208; nema17 engine; tft35 v1.0 screen; two titan extruder with E3DV6 in bowden; all working with smoothieware.
The smoothieware part is almost finished (it remains only to integrate the cnc part. On the other hand for the screen it is another pair of sleeves, I manage to find a cnc or laser or printer firmware but not one that would do the 3 at the same time.
Do you think it would be possible to merge the three into one (with a selection menu or any other viable method).
I hope I have been clear enough, thank you for having me and for the future answers you will give me.
