I would be in for an 'upgraded' K-line tooling sourced J1e Hudson, a PRR H10 with the taller tender and better silver paint, a revisit of the PRR M1b, a scale camelback possibly, and a Lionel Lines baby Hudson with die-cast 6-wheel 2046 tender - can be conventional, or LC 2.0 whatever.
Any small legacy steam would be considered.
