I and others have been experimenting with Amelanchier for pear rootstock.
It is very dwarfing and quite precocious. It isn't perfect however as another grower has found that you should leave a shoot of amelanchier to grow as well as the pear scion as the rootstock just isn't that happy to have a pear on it. My own grafts just sat there for two years before finally showing some vigor this year.

I've got several pears growing on cockspur hawthorn(C.crus-galli) rootstock. Oldest one on this is a graft of Ubileen, probably 4 years old, looks quite healthy, with good branching, but is only about 5 ft tall. No fruit yet. I'm somewhat concerned about the possibility of the tree breaking over at the graft union at some point in time, as the pear is quite a bit larger, already, than the hawthorn understock.
Have several pears grafted onto seedling apple/crab rootstocks(purchased as P.communis seedlings, but they weren't). Magness and Warren look OK, but Luscious and Ayers evidently don't 'like' apple - or, maybe the apple doesn't like the pears. Ayers grew like crazy the first year, but has stalled over the past 3 years or so, and is now declining. I've re-grafted it onto an OHxF rootstock.
