Moving a -50 penalty site to a new domain

[SEOPTI]

I own quite a few domains/sites which are in the -50 box. I think the sites have been manually moved there because they did not have a good design and not the same functionality other sites which rank have.
I'm sure in my niche manual reviews play a big role.

Since reconsideration requests have been ignored by Google and the improved sites sit in the -50 for a few months, I really need to move them to new domains since I don't want to waste the content on penalty domains.

What I plan is to request a removal of the old URLs in WMT, then wait until this removal has been completed. Once no URLs from the old -50 domains can be found in the index I will move the content/site to the new domains.

Has anyone experience with moving a penalty site to a new domain? I will test it and report back, the main problem I see Google probably could still have the old content saved after removal of the site and compare it withe the content on the new domain.

What about the internal structure? Did you label articles in two categories? Wrong categorization is a death trap for dupe content.

What about relationships between inbound linking sites?
