Blimey, this is hard work! Read again "Because V1 can't be greater than Vr - once yr past that, you're airborne and RTO is no longer an option. If you (knowing yr ac capabilities) decide that up to eg 50',100',200' whatever you plan to land back on straight ahead then that's a different matter"
I stick by that - if you are able to land back on and stop safely then why not? I guess you would probably have to initiate that before gear retraction.
The important thing is to make these decisions before you set off down the runway. So perhaps (not knowing yr aircraft type so doinbg a read across from my previous experience) the following might work (having considered the runway/weight/wx etc on the day) "up to rotate I shall carry out RTO iaw with our SOPs, after that before gear retraction I shall lower the nose and land on the rw remaining. Once the gear has started to retract I shall continue with the SID/carry out SOP EFATO actions whatever etc etc."
Hope this helps
