RS180 version of the Thor cabinet revisions?

[crazyjpeters]

Forgive me if this has been asked already.

There have been several posts referring to an RS180 substitution of the Seas drivers in the Thor cabinets (the fixed ones).

I'm interested in doing an RS180 natalie-p X-over, and the short-Thor revision looked like a good option, but I am curious as to whether this would require a further revision to the already revised cabinet.

Would this be a good path to go down, or is the revised-Thor a thing of the past / poor option?

Thanks,
