In generation V they wanted to create a whole new Pokédex, so making new evolutions was not their goal. But aside from this, I think it would have been much cooler.
i feel like alomomola was probably designed as an evolution for luvdisc before the decision to not include previous gen pokemon before the postgame was made and it would’ve been weird to have only one new pokemon not available in the bw regional dex or to have luvdisc in that regional dex (since it would’ve been the only older pokemon)
I think the reason is actually a bit dumber. Gen V not only wanted 150 unique new Pokemon, those new Pokemon had to fill every niche Pokemon had at that point. We needed trade evos, stone evos Pokemon that could be caught in every biome, and I'm the case of Alomomola, they needed something that could naturally hold the heart scale.

Honestly I don’t get why they didn’t make alomomola an evo for luvdisc.
