Tail configuration and power system have little to do with the CG requirement.

If you have an adequate tail surface area... the proper CG will be within the normal 25% to 35% MAC range.
If the tailplanes are small and/or close to the main wing... you might end up needing to go with the flying wing range of 10% to 20% MAC.

Airfoil and incidences have more effect on CG range than the tailplane shape/style.
The engine placement will only change the thrust lne requirements. (and where the other stuff goes to get the correct CG....)
