[MCU] Can Steve Rogers use time travel “incorrectly” to become young again?

If you remember, in Endgame, when they were first trying to send Scott Lang back in time, he came back as a baby, an old man, etc. is this something that they could use to make Steve Rogers young again in case Chris Evans wanted to come back at some point?

Yes! That was such a neat accident, especially considering how it happened twice and Scott survived both times. This must be reproducable. It is canonically possible through science to change your age in the MCU. But the machine is destroyed and Bruce got a lecture on screen from the Ancient One about time tampering. If the age machine angle gets explored any further it won't be the good guys rebuilding it.
