Verdict
Full re-application
There is nothing at the state level to transfer your Illinois license into: Wyoming issues no statewide plumbing license, so plumbers there are licensed at the contractor level or by cities and counties. Not applicable at the state level — Wyoming issues no statewide plumber license, so there is no state exam to waive or transfer. Each municipality sets its own exam and rules; e.g., the City of Cheyenne requires passing an ICC National plumbing exam (or an equivalent trade exam) and offers no reciprocity, so an out-of-state license is not transferable through any state agreement. The move is a local or contractor-board application, not a reciprocity filing — identify the authority that governs your worksite and work from its exam, experience, and fee rules. Your Illinois license may count toward a local experience requirement, but Wyoming has no state credential for it to reciprocate into.
