If you do not want to make huge changes, imho there is a merit to play
1♥--1♠
2♦--3 any M
as forcing.
You may feel like you are sacrificing your 3 card ♥ fit and invitation hands, but most top players that i know has already added them somewhere else in their system, and if not you can always start with 1NT and then 3 ♥. Price will be to give up on 4-4 spade fits when you have a 4 spade and 3 heart inv values.
. What Zel said about playing 1♠ as forcing NT, if i recall correctly this was called Brazilian forcing NT or something like that, which i played for long time, and was created actually to handle the Flannery hands w/o having to use the F convention. Using this, you would not even lose your 4-4 spade fits. 1♠ as forcing NT has its own minor issues, but nothing more than any artificial bid which replaced a natural bid.
In another recent topic, just like Kenrexford i suggested to start 2 ♣ over 1♥ when we held a 4 card spade and a very strong hand and i was lol ed. And the hand in debate was much more suitable for 2♣ than this one. Because i could have used it there w/o having any relay or artificial agreements for continuation. On this type of hands here, as she said, if you are gonna use 2♣ you will need some serious changes on your continuations and i am not really a big fan of making huge changes each time we miss a slam.
As a side note about strong jump shift, i would rather miss every slam out there and not play it. Don't get me wrong, i am not saying it is bad thing to play SJS, it is just not in my blood i guess. Same goes for F convention, it is not as bad as people make fun of it, neither as good as some others love it, but definitely not in my blood either.
EDIT: sorry i missed the part below

What do you think? Outside of changing our system (ie secondary jumps forcing or an obscure convention) is there any other way to handle this hand using expert-standard-ish 2/1?
