I don't think that he'd even need to be born on the wrong side of the blanket, he'd always be not entirely a Time Lord and therefore have a huge target on his back that way.
Ruin is probably too strong a word, it's more like 'make even more awkward the chronology' because in the first Master episode he's introduced as just another Time Lord and it's only later that we get the whole thing about them being friends at school. Them being brothers would also jar with other things like (both from the bbc website)
>>Untelevised The Doctor has been to a circus. At some point, he angered the Master enough to make him want to kill his 'old acquaintance'. The Master's hypnotic skills were evident then, although he was not nearly as learned as he is now. [Their time together at the Academy wasn't very important to them (the first Doctor doesn't recognise him in The Five Doctors) so the antagonism must have arisen during unscreened later meetings.]<<
Although some of the later 3 and 5 stories screw that up too, so I probably shouldn't complain.
And while I can buy the Doctor eliding his relationship to his brother by ignoring it totally, or just saying he's another time lord to give as much detail as he does do in 'The Daemons' seems to defeat his purposes if that was his intention.
>>The Doctor : [Speaking of the Master.] "He used to be a friend of mine once... a very good friend. In fact, you might almost say we were at school together."<<
While you could quite easily spin their relationship into the Master being the older, full-blood brother and the Doctor being the younger, almost, as you say, bastard son, kind of like Prince Michael and King Rudolph in 'The Prisoner of Zenda', I've always seen them as being very similar to Ethan and Giles.
Plus, if they are brothers, it weakens my joke about all the interesting/loony time lords being from the Prydonnian Academy.
Probably far more rambling about the Doctor and the Master than anyone should be subjected to
