You should be able to find a chain length that will accomodate both a 46/15 and a 49/15. Set it up so that with the 46/15, the axle is close to the back of the dropout. You should then be able to get the 49/15 combo to fit without changing chains. You can usually find half links to more finely tune the chain length. Even with my short track ends, I can cover a four tooth change in chainring/cog combo.
