I think you've got a wonderful opportunity here to try out a few different things.
Only suggestion I have is that you make sure that whatever you intend to do, dig and move, trunk chop, air layer, etc would be to make sure that you do it at the right time of the year. Now would be an excellent time for you to research this species and begin learning about it's timing. There is a best and a worst time to perform each of these things for each different kind of tree.
I think these trees could provide some excellent learning opportunities for you.
I dunno if you've found this site yet or not, but
http://www.bonsai4me.com has some very good writeups on many techniques you could try out on these trees.
Have fun with them!
