Would the following trick make mixed mode unnecessary?

Say your program uses Decimal, but imports several old libraries
that know nothing about Decimal. Say you tell the compiler to
compile these old libraries in an all-Decimal mode. You just
force them into Decimal, ignoring the fact that they were
written for binary.

If /everything/ becomes Decimal, the whole language, is it
likely that the libraries will have a problem with this?
Isn't it extremely likely that they will just work perfectly?

I've mentioned this before, but I'm not sure if I was clear
and understandable. Forgive me if I'm repeating something
that isn't useful. As a naive onlooker I think this /sounds/
