A great deal depends on what the company is willing to pay for the Paris meeting trip.
If the company is willing to pay full business D ($7600 plus taxes from PHX-CDG return) or even J (much higher) .. then a RTW fare in J will cost almost exactly the same (and F maybe only $2k more) for a three continent hopper (more for more continents).
I am in the process of confirming a MSP-ORD-PVG trip that is over $13k in J if I just come back. Compared to $7600 (or $9600) if I do MSP-ORD-PVG-LHR-ORD-MSP as a DONE3.
Many times when the traveler has a few extra days, RTW tickets are much cheaper than return premium tickets. I personally think the OPs idea makes a great deal of sense.
Now doing a RTW in economy would be sheer crazy IMHO.
