I doubt it. Recently downloaded the latest version and it only had support for 10.98 (last protocol I could actually browse to find .spr and .dat files). I haven't been in this scene for quiet some time, but I found there is no .spr and .dat files with latest Tibia clients, that might be an issue to the map editor.
EDIT: might have found something worth reading for you, I just managed to come across it on this forum:
OpenTibia - Client 10 Version 11.55+
Seems you allready was on that information. Apologies.
