Sounds good!
For the record, first most of the Change Gears on the Atlas lathes, mills and shapers have part numbers beginning with one or two digits and/or letters (which ID the first machine that the part was used on) followed by "101" followed by the two-digit tooth count. The four gears drawn to look like compound gears but having four different part numbers shown are each just 6" Change Gears. Loading them onto an M6-70 double-keyed bushing turns them into compound gears. So it is possible that M6-101-20 could have been bored out and turned into an MF-101-20A. But not knowing the ID of the latter versus the ID of the key-ways in the former, I can't say whether or not the boring would have cleaned up the bore of the gear. If it did, then it would have worked.
But fortunately, you didn't have to find out!
