Why anybody would prefer a mod that offers no flexibility in power output and no protection, aside from following a trend and for the reliability of a device that has the simplest type of electrical circuit short of, well, a short, is beyond me - but that's just me. However, if you make a "hybrid" mod such as the one you describe, your device is neither hip nor reliable, and will appeal to neither the APV crowd nor the mech crowd.
If it's what you really want however, buy an APV, open it up, and add a switch to disconnect and bypass the advanced electronic circuit at the power supply. It's trivial to do.
