Keith, based on my direct experience with my XT10i on an RTP platform, it is totally doable...

You don't have to drift align the platform... I posted a while back on how I did my polars (and how I modded my RTP to make it dead easy)...

If you do that mod, all you then have to do is just ensure that your finder cross hairs are on Polaris, and you are close enough to do 56 seconds (in my experience).

Others use very large dobs (using ServoCat) with much success...

So, I'd say, "go for it"...
