I know that the 62As on the Metropolitan Line are due to be replaced
in the next year or so. Would they not make a more suitable
alternative for the Island Line? Would the loading gauges be an
issue?

Yes, there's a very low bridge[1] in Ryde that requires the use small
stock, hence the reason for choosing tube stock in the first place.

[1] And possibly others elsewhere on the system.

Have they always used Tube stock on the Island Line since its
electrification in the 60s?

Yes. In order to cope with flooding in Ryde they had to raise the track to
the point where only tube stock would fit. From electrification they used
Standard stock and, since 1989, 1938 stock.
