I'd say yes, but you have to be carefull. Here is how I did it.
First I uninstalled fb15, then I searched my entire drive for
gds32.dll and fdbclient.dll, and deleted them.

Then I installed fb2 into c:\firebird. I did NOT setup the service
and I did NOT copy anything to the windows/system folder. I made sure
a path was added for c:\firebird\bin. (that way programs use the
gds32.dll from c:\firebird\bin).

Then I renamed the folder to c:\firebird20. Then I installed firebird
1.5 the exact same way.

When I want to switch, I just rename the folders (well, shut down the
program first (It should be running as an icon in your system tray)).

From firebird -> firebird15, then firebird20 -> firebird. Then I
startup the program (I usually create a shortcut to fbserver.exe with
the -a option and drop it into the startup folder.)
