I am surprised your DM would feel hamstrung by that. The designers have, in several places over the past two years, stated that the druid limitations were strictly for flavor rather than balance, and similar could be said for other minutiae (the monk and paladin multiclass restrictions, for one). Even if we did not have the opinion of multiple designers stating this, every DM should feel free to change something about a class that they do not agree with. It should not take a whole redesign of the druid to get around it.
Even if he felt unsure about allowing a multiclassed druid better weapon restrictions, He can make some sort of minor limitation to make up for it. Even if he didn't keep in mind that owning the weapons does nothing - using them in combat means that all spellcasting powers are lost of 24 hours - not good, but not the end of the world.
My advice to the DM is just let a multiclassed character have his freedom. After all, clerics are not hampered in this way, so why should druids be? And keep in mind that clerics, power for power, actually have the edge on druids.
