We’ve got a lot of irons in the pipeline

This is a conflation of “in the pipeline” (plan being developed) and “irons in the fire” ( a number of jobs or possibilities available at the same time).  I saw this in a memo years ago.  As with most great unintentional malaphors, if you heard this at a meeting it might give you slight pause but it fits in the context so you probably would not remember it minutes later.
