You don't need a mempool to send a transaction. You can just open
connections to random Bitcoin nodes directly and try sending your
transaction. That's what a lite client is going to do anyway. If the
pinned transaction is in the mempools of a significant number of Bitcoin
nodes, then it should take just a few random connections to find one of
those nodes, learn about the conflict, and download the pinned
transaction.
If that's not acceptable, you could find some other way to poll a
significant number of people with mempools, e.g. BIP35 mempool messages
or reusing the payment hash in a bunch of 1 msat probes to LN nodes who
opt-in to scanning their bitcoind's mempools for a corresponding
preimage.
