This is not generally a good idea. While converting from Aeroplan to some programs like US Airways can be done without too much loss of value, the reverse isn’t the case.
The bonus doesn’t just apply to transferring miles from one program to another but also “trades” that occur on the site between members. Those are also not a good deal given the cash costs required to transfer.
