I'm really not familiar with the Angel's Shadow construction, but my opinion is that it is harder to do a light conversion with a model that has a belly pan. With an electric, there is no need for that, and in fact it makes it a requirement to install the batteries by removing the pan, sort of a nuisance. It's much easier to simply remove the canopy hatch and install them through that. In fact, in the Partner my canopy hatch is held down with a BVM hatch latch, making it really easy.

I have a PL Lazulite kit, and if I build it for electric I will glue the pan on and cut out the divider. Have to come up with some neat arrangement to lower the LG mount, also. With the AS conversion, you will need much longer LG legs to clear that 22" prop.

I'm sure some will do conversions of existing glow models, but IMO you won't see the real benefits until you build an electric specific model. If I were you I'd enjoy that nice Angel's Shadow as it is, and maybe think about a new model for electric. I'm hoping the coming Piedmont Splendor will be suitable.
