Seems we are doing very similar things: https://bitcointalk.org/index.php?topic=1340621.0 (also based upon TierNolan's basic idea but reworked to use CLTV with P2SH so no malleability issues and txs should be considered as "standard" for both Bitcoin and Litecoin now).

If you would like to use some of the CIYAM code to get your implementation using CLTV and P2SH you would be welcome to (also feel free to PM me if you wish to discuss it).

Also if you are doing a GUI then with some very minor tweaks you could get it to work with AT blockchains as well (Qora and Burst) as they have supported ACCT for a long time now.
