I also agree that gliding is very much real flying, and every bit you do will be worthwhile.
You're already a member of SUAS, so that's a bonus although I know that UAS flying isn't what it once was.
You are a short train ride from Popham (which is about a mile from Micheldever Station) and Chilbolton is also not far from there, two very friendly flying clubs, both of which are usually full of experienced pilots happy to have somebody in the right hand seat. Not usually loggable, but why not go and make yourself known, and get some flying experience that will be both fun and useful to you.
