Domained Joined Hyper-v question

I have a question, it may seem odd. I am adept at Hyper-V, just need to verify if my thoughts are correct.

I have 3 MS Hyper-V hosts. I have 3 Domains. Currently only 2 of the 3 Domains are in use.
We will call them Domain A,B,C.
Domain A is broken, the old I.T. company had shared permissions to sysvol all messed up and cryptolocker ate them alive. This Domain has 2 Hosts with all the production servers.
Domain B is a domain i need to decommission because the company bought out this company, however they still need access to one app server in the domain.
Domain C is a fresh Domain i created to start them off with a clean slate.

I would normally build a trust relationship to move the host and VM's around, but Domain A is to broken for that scenario.

Now for the question can I join the Hosts from Domain A and B into C, without any major repercussions on the current infrastructure. I need to Open a host up for Vmware conversion, while leaving the Domains intact for the moment. Remember A wont talk to anyone properly and I run into a permissions issue when trying to manage the hosts from any other Domain.

I am up for suggestions!

Thank You,
Marc
