I wouldn't recommend the GSO 10:1 low profile focuser. From what I have seen they have issues with tube sagging under weight.
I think the standard GSO 10:1 would be a great focuser. And from what I read in this thread, it would probably come to focus. By that I mean you would be able to sit the MPCC into the GSO focuser and this setup would be similar in height to your existing focuser.
Might be easier and better than trying to machine a new part. If you imaging, your going to want 10:1 focus eventually.
