I have a converted X1 mill and an almost complete larger CNC Router build, I also own a small model makers metal lathe 7x14 which I have considered not worth a conversion.

What I have been toying with is the idea of mounting several tool holders and tools on the mill bed and Mounting a lathe spindle in front of the bed so bed can provide multiple tooling options at any one time maybe 3-5 loaded at any time I understand limitations on size of work that could be accomodated. The X and Y axis being driven to engage tools from in front of spindle (in/out and side pressure as required), I can see the programming may be complex a lot of offsets to use but not a problem so is this solution workable or am I missing something major in my approach.
