I don't know
But I am so going to try that.

I had a look into it

Requires low/high pressure for degassing and impregnating the wood after the lignin is removed though.

Yep
I guessed that the impregnation would be the difficult bit. I suspect it will need to be a very low viscosity resin as well. Every time I tried using vacuum pumps at work for de-gassing experiments I'd get shouted at for putting dodgy gases through the pump which could affect the oil and bugger up subsequent experiments.

Given the problem of removing the lignin from a solid block as well.
Using Kraft paper pulp it would be easier to mould/bleach as well as impregnate.
Not terribly 'green' given the chemicals and energy required and not recyclable in most cases.
