i think a little more power is always good in emergency's but in moderation.the problem is how much more weight it adds to the front end.that makes them come in a little hot and nose heavy.one advantage is you can use a larger prop but landing gear problems might be an issue.look at the design of the kit or model and decide where it might need to be strengthened.most of my models are kits and i always make a few changes we all do.....happy flying
