Seriously not worth the effort- you'll destroy the internals of the gun, then have to spend 10 times as much upgrading it. Heck, you can destroy the internals just by going to lipo from nicads/ nimhs. There has been talk on Arnies Airsoft about lipo and BL powered guns, but in all seriousness, just upgrading the stock motors to a better version (think 540 silver can to 19t tuning motor) gives you a higher Rof and power output than you could possibly need, not to mention if you go too fast it causes issues with the gun feeding ammo quick enough = mushed ammo inisde the chamber, not fun to clean out.

This is one of those times where BL is not a good upgrade...
