Kentrosaurus for Boss Battles?

[LapisOre The Mothman]

I play on my singleplayer server (sometimes with a friend), which has boosted all stats of tames a bit. I currently have one Kentro with 25,000 health and about 2000% melee damage (was level 145 when wild). Could I get about 3 more of these and use them against the broodmother? (along with a Yutyrannus and a few Spinos, of course). They have a damage reflect thing that could be useful.
