If it fits without modifying the lenses, then go for it. It's worth a try.

+1 on that!
I succesfully swapped elements before, made 1 good one out of 2 bad ones. Do some testing afterwards to check if all is okay!

Hi,
I have a Biotar with 500 blades and a front element in a shape that it will make one cry!
Does the alleged "biotar copies" will fill the gap, or there is another option apart buying a new one - which makes few sense in this case,
[]s,

Nothing to be lost by trying it - if it doesn't work 100%, it might produce something that turns out good for portraits or novelty value, at least.

optically speaking it should be possible, not sure, actually rather doubtful if it will be possible 'mechanically' though. Looking at the rear of a Super Takumar and an Pentax M 1.4/50 not only, of course, the mount is different but the whole 'casing' looks quite different and I am pretty sure one could not just exchange that. That is, if swapable it would be the glass element only and again I am not sure if these would be 100% identical so that they would fit in a 'different' housing
( btw. I just received a Tokina f3.5/17mm I had bought to use it's rear element to substitute a damaged one of an otherwise good Vivitar f3.5/17mm in a more convenient mount. Turned out that this is not possible. The whole construction of the rear element, even the size of the glasses are so very different that I now doubt, can't imagine that, as one can read so often and generally is believed, these two lenses are optically identical. )

Currently looking for a salvagable super tak at low price whose most rearest element ois in good condition!11
