I don't think so - most tours that visit the Taj incorporate other bits of north India, especially Delhi and Jaipur (Delhi's a bit exhausting, but Jaipur is nice). I don't know about the Maldives; it seems a long way just to go to a beach.
But there are companies that will tailor-make you a holiday wherever you want to go, eg Cox and Kings

Trailfinders can probably do it too; they arranged a tour of Cambodia for me this year

They won't be as cheap as a standard package, though.
