Again, why not? There are only 3 things to be addressed when playing in any official capacity; WYSIWYG, Modeling for Advantage, and usually a 51-100% ratio in favor of Official parts of model to 3rd Party/custom.
Special precautions could be used to ensure there is no "modeling for advantage", by just replacing its base which would put it on par for height really. If there are any worries about WYSIWYG that can be addressed as well rather easily. The only reason to disallow it as long as it provided ZERO change in actual gameplay is if you want to be a *insert choice word here*. Most Tabletop wargaming communities follow these same rules, so I assume the SW:Legion community will as well.
