You could make your BA run on NETX v4.5 and carry NETFX v4.5.2 in your Bundle. 
Thus if the user has NETFX v4.5 then v4.5.2 gets installed as just part of your 
Bundle.

Thanks Bob,

To verify my understanding, since my bundle is going to require .NET 4.5.2, I 
should also make that the prereq for my MBA?

If so, I guess the disadvantage I see to this is that most users will now see 
that prereq UI instead of just seeing my custom bootstrapper UI.

Thanks,
James

The pre-req BA works like this:

1. Load MBA. If success, goto 4.
2. Execute chain.
3. When WixMbaPrereqPackageId package has been installed, goto 1 or reboot if 
necessary.
4. Run MBA.

It wouldn't make sense to bundle one version of the Framework and install 
another one just for the MBA, so WixMbaPrereqPackageId is used for both.

As for the missing variables in 4.5.1 and 4.5.2, see 
http://wixtoolset.org/issues/4180/.
