I too have an AS (OS) and am finishing one up for a friend (YS). I don't think it will be easy to convert, mostly because there is hardly any room to work on the firewall to convert it. Also, the batteries in the bottom of the fuse will be a BIG pain to get to through the chin, and I don't think there is any room to get them in through the canopy. If you've got one that light on glow, I'd leave it....
