I don't think I've ever seen two shunters working together on one rake of wagons unless you count class 13.I was under the impression that yards with multiple pilot engines involve simultaneous working in separate parts of the facility rather than doubling-up for the purpose of tractive effort.
If there are too many wagons for an 08 to shunt at once it would almost always be more efficient for to split into two rakes and shunt them separately, either sequentially with one shunter, or in parallel with two if available.
The best example of the latter were the train ferries at Dover, which needed careful co-ordination to load or unload both tracks at once to avoid the ship listing.
