That's actually a pretty good idea and I can't imagine it would be that hard to implement. I do think a lot of the problems could be solved just with a bit of balancing, like reducing the health of summons and giving them the "Stench" talent so they're not all so tanky, but this is another interesting idea. It means you have to set up a summon instead of just being able to summon any of them at any time, and your positioning of them would be limited to the surface. You could have to summon a skeleton from blood, also. Multi-elements like electrocuted water of frozen blood could have either elemental type summoned on them. Not sure if the spider should not require a surface; could be a unique trait to it (but make it a little weaker than the others to compensate.)
Also would give you more incentive to disperse surfaces around enemy summoners.
Only downside I can see is that it would make it a little harder to summon earth elementals for their perception, but I don't think that's a big deal.
Another random idea is that you could "charge" a summoning scroll with the appropriate essence (e.g., fire essence for fire elemental) to make it so you could summon that elemental anywhere.
