That is very well possible, but I would have to take the chance that
it will fail again in a few years.

Maybe I'll try, it would be a relatively quick fix at least (cutting
out all the old seams and replacing them with fish tank silicone).

But then, a completely new tank would allow me to fix things that
aren't perfect, and add a couple new flaws. ;-)
