Work Train with Fireman's Car and Fish Tank Car. I also have the original Black and Gold work Caboose, that was the option on the original Lionel work train set. The Black & Gold with red trimming NP work Caboose, matches the original Lionel NP Engine perfectly. I might just make the original NP GP7 Engine into a non-powered unit, to run behind my new Legacy GP9, making a double header GP9/GP7, we will see how they look together, definitely with the original Black & Gold work Caboose.
You might still be able to find one of the original Lionel Black & Gold NP Work Cabooses on line for your train set, however I have seen very few of them. I will let you know how the Legacy sounds and runs, you might just want to make it part of a triple header, set up.

I probably wouldn't MU these engines even if I had the Legacy GP, because unfortunately Legacy and TMCC engines don't run together well in MU setups. Not sure if by "work caboose" you're referring to the bay window cabooses. I know that after the Postwar period, during MPC days, Lionel made a green and yellow NP bay window, which was the prototypical color. But (according to Greenberg's) collectors wanted Lionel to make a caboose that matched the black and gold GP engines Lionel was producing then, so Lionel proceeded to also produce a black and gold bay window caboose, which of course is a fantasy scheme.
These MPC engines (like the Postwar version) also used a non-prototypical gold paint rather than the correct NP yellow. Using your original Geep as a non-powered unit to run behind your Legacy unit, as you mentioned, may not look very good, given that one has yellow paint and the other has gold paint. I was never sure why Lionel used gold paint on these older engines instead of the correct yellow - just one of those Lionel peculiarities that was begun in the Postwar era, I guess. I'm glad these newer engines use the collect yellow color.
I was fortunate to pick up both the Atlas cabooses several years ago, but already have those assigned. For the LionChief+ Geep I may use a Lionel woodsided caboose I have, or else get an older MPC green bay window to run behind it. Incidentally, here are pictures of the various cabooses mentioned.
