I would rather not deal with a rubber band wing either. But when faced with the decision of:

1. Do I spend the time necessary to modify an ARF to a bolt-on wing, or...

2. Get the model ready to fly to mollify a seven-year-old who has itchy britches and wants to fly NOW...???

With the LT-40, I chose number two. I just ordered him a Midwest AeroBat that he doesn't know about yet, for his tenth birthday. I might take the time to convert that one to bolt-on; but then, I just bought a new one-pound box of #67s from Sig. Hate to see them go to waste...

You're right; the price of those li-po packs is larcenous. I alluded to that in my first post in this thread. One can indeed have e-power equal to glow; but you're going to pay dearly for it.
