A fun idea indeed! This is actually quite doable today (though not necessarily advisable). No fancy UI/UX is necessary though. Rather we can just a generate a big list of addresses. Then you can use the "send to many" feature in a wallet of your choosing you can send sats to future miners!

The locking script is a simple anyone can spend script <blockheight> OP_CHECKLOCKTIMEVERIFY When we wrap this script in a pay2sh or pay2wsh output (so that any transactions sending funds to it are still considered standard), then this means that future miners interested in spending such an output would need to know about it first or how to derive/check similar addresses, but it is not hard for them to do so.

Here is the pay2wsh address for a blockheight that will unlock somewhere near year 2140:

block number 6973063 (approximately end of year 2140): bc1qmqckte0sfhh8xyc6v7zswrs5mpjrrf2f5frwe2yz68lyy253m7qshzrdqn

Here is the code I used to generate it: https://gist.github.com/VzxPLnHqr/acc4fd4ee399196e7723a7d36a90834b#file-pay-to-future-sc

Note: I did not have a chance to double check these. You should probably not send money to these addresses. Rather I just wanted to demonstrate that it would not be hard to create such a list, either statically or on-the-fly. There are also other types of addresses which would likely be cheaper from a fee standpoint.
