Bosch H1 Headlights

I have H1 headlights in my 72T, they are the later lens with the lettering on the inside of them.
My problem, ( I have many ) is that they are for LHD and not for RHD. ie the "slice of "pie" is on the left.
I cannot purchase RHD H1 ( 'pie on the right) replacement lens and am wanting to know if the H4 lens will work on the 2 bulb setup of my H1 headlights???.
Am aware this topic has been banged about heaps but I cannot find an answer to my particular question.
Many thanks in advance
Regards
Mark
