Default Planing a stabilized board

Probably a long shot but was wondering if anyone has ever run a stabilized board thru a thickness planer. I managed to pick up some hard-to-find plum wood that I sawed into around 6 dozen boards about about 5-6" wide by 15" or so long. Then placed them in a vat of DA for a few months. Pulled them out and stickered them till dry. The issue is over half of the boards have splitting to some degree which plum is supposedly prone to. My idea is to dry these in an oven in a jig to hold them to the same dimensions as much as possible and then stabilize them. I don't see any problems overall but I'll have to joint and plane them for what I want to do. Anybody done this or have any insight?
Thanks.
The pic is of a few of the boards, it's really beautiful wood.

Got access to a thickness sander??? The kind with a rotating drum and feed belt.

I tried to use a hand plane and discovered quickly the value of the Jet thickness sander.

Thanks for the reply. Don't have access to a thickness sander but that sounds like a great idea.
I've got 3 of the boards clamped and in the oven right now and I'll be stabilizing them in the next day or so. I don't have a vacuum chamber big enough but I do have several gallons of cactus juice so I'm going to submerge them in that and see how that goes. They're all about an inch thick so it'll be interesting to see how the CJ penetrates as opposed to a vacuum. From there I'll run them thru the planer.
May look into building a vacuum chamber out of large diameter PVC. Have no idea if that will work though.

Personally, I wouldn't send them through any planer that I owned.

You might be able to rig a plastic bag to pull the vacuum. The viscosity of the cactus juice will limit penetration with just soaking. Try small scale test first. Or use large pvc pipe.

that's what I'm concerned about-if stabilized woood would rapidly degrade the planer blades. I'm going to follow thru with soaking the 3 boards just to see how well that works. I just need them to be stable enough to stand up to machining because some of the most interesting boards are the most fragile.
I thought about vacuum bagging and I need to determine if that will be effective for what I'm doing plus the time and expense setting all that up.

There are vacuum stabilisation bags on the market (Packard Woodworking sells them).

They need different plumbing on the chamber lid from the standard one sold by Curtis.

Sounds like you are getting caught in the "if all you have is a hammer, every thing looks like a nail" perspective. Once you partially treat with cactus juice and bake it, the cactus juice plugs things and success at reprocessing plummets.

plugs the wood or vacuum bag equipment? not sure what you mean but thanks for the link-there is interesting stuff on that website.

Cured cactus juice plugs the holes near the surface, and blocks or slows the future efforts.
