Now from different point of view: balance.
From what I know, your server is rather low-magic type. Are you sure you know what are you doing? I must tell you, as a developer of an epic action loot module I was considering this change and decided not to do it from balance reasons. See the AC is something that druids/shifters do not lack. One monk level and AC gets increased extremely. And this is not just lvl 40 issue, a lvl 15 druid/shifter/monk (IIRC) can get over 50 ac in kobold form with HIPS.
Stacking abilities, or even skills is fine and possibly preffered by majority. But unless you somehow disable monk AC, you will get a balance issues with shifters and their AC soon.
Also merging gloves properties into "unarmed" forms is something that can cause a big balance issues. Of course it depends on a strength of the gloves, the default ones are fine, but many modules have a better gloves to balance them with kamas and if you use such gloves in a polymorph, namely dragon form this might get problematic.
