J&M use to make a handheld mic for wings. If the plugs are the same, it should work. You might find one with a search. eBay, amazon, Pinwall.
The plugs are the same.
The wiring, however, is not...as I've pointed out.
That mic worked with the older Type 1 and Type 2 'Wing setups. It will not work "as-is" with the Valkyrie (either the I/S or the accessory Std/Tourer CB) without the addition of a keyer interface and another (dedicated) connector.
