Seeing how this strongly ties in with your other question about publishing and bundles I would suggest using an event system to intercept publish operations on bundles and break them up into individual items. You'll lose the transactionality of bundle publishing but also the problems of increased package sizes (and your bundle will publisher in a shorter amount of time assuming it's the only item being published).

Note that breaking transactionality of publishing CAN be a very BAD thing so make sure all stakeholders involved understand the consequences of this decision...
