If you generate 202 or 203 lines, progressive scan, 50Hz field, it will work just fine. The only thing you won't be testing is how well the sync separator is dealing with interlace.
I'd wondered about that, but having never done it... There was 405 TX still in 1972!
The 405 only sets still popular then as bedroom sets because not much extra on BBC 2. Colour was still not universal even for 1st sets, though we had a colour set then. I had one 405 set in our Kitchen for a while. I'd get them free, fix them (ineptly) and sell in Belfast Telegraph Classifieds as BBC1/ITV only bedroom etc sets.
Edit: Of course back then it was reasonable on dual standard models to remove knob/lever and solder contacts on the big switch in 625 position. Sometimes two switches: the IF /Video/Audio one side and timebases /frame/line/LOPT on the other.
