Locating a 6s5000 pack in the tank compartment is a non-issue as they’re smaller than a 16 (even 12 in some cases) oz tank. Some weight redistribution of the radio may be needed due to the additional “nose” weight brought about by the motor/ESC/LiPo combo which weight more than an engine/tank and fuel. Wisely locating servos and the radio pack usually solves this problem including the possibility of installing twin elevator servos in the tail boom. Sometimes the radio battery also needs to sit behind the wing TE under a hatch much in the same way that the tail servos are located in the MK Skymaster.

A little creative former redesign and lite ply floor additions in the canopy area can produce a removable assembly for access to the LiPo located on a tray with the motors ESC just aft of the FW which can be moved forward a fair amount given the requirements of 50 mm can outrunner.

Also, Mike Seale scratch built both a BA as well as an Atlas using the same electric retracts and electric power systems. Here are the build logs and an excellent reference:

Hi David,
Thank you for your valuable and timely reply. Earlier today, a club mate (a very experienced builder) and I were discussing today how to make things fit and how we would need to modify the internal structure and your reply could not have come at a better time. I will write to Mr. Seale and ask if he could post some photos of his motor, ESC, and battery bay areas and see if he has additional detailed info he could share.

We were thinking of increasing the size of the plane by 10% , a scratch build, that would provide more space, but it appears with Mike Seale's success that will not be necessary.
Again, thank you.

Francois
