My first thought is maybe you could keep bip37 filtering as optional for unconfirmed transactions. Since you're only interested in incoming transactions in this case you can create one big filter with all your wallet's addresses and reuse that filter. The bip37 privacy issues mainly come up when trying to get the filter to match both incoming and outgoing transactions, which is not needed in this case. Otoh, if you download the block from the same peer that you gave a bip37 filter then they could probably test the txs in the block against both filters. :/
