Is there a way to build HTLCs or PTLCs that can be unlocked using different preimages or signatures?

Or: Is the equivalent of a 1-of-n multisig possible with PTLCs?

Is there anything remotely related to that for HTLCs?

Yes, think so - you’d put all the different unlocks in a modified BIP199 HTLC script?

Something like

```

OP_IF

[spend with a pre image (hash)]

OP_ELSE

OP_IF

[spend with some multisig and CLTV]

OP_ELSE

[spend with weaker or other multisig and longer CLTV]

OP_ENDIF

OP_ENDIF

OP_EQUALVERIFY

OP_CHECKSIG

```
