This is the largest problem with summoners and mostly always has been, and has never really been addressed. (Summons not attacking out-of-los makes it slightly less powerful to walk around with a permanent army, but it's still vastly superior to walk around with an army compared to walking around solo, so it didn't really change anything.)
1) I'd rather see summons just be weaker per-cast than to invent a special new mechanic that only affects one spell type for no real reason.
2) would not really be a problem either ... it's by design that the summon cap is per-spell instead of overall. The intention of the summon cap is entirely to make the player use more than one type of summon. Making the cap a total amount of summons would do exactly the opposite--you would very strongly prefer to only use the summon spell that is the most effective per-summon. You can argue about whether attempting to make the player use multiple different summon spells is a good idea, but that is the entirety of the reason the cap exists so you first have to convince the devs to reverse course here.
(The largest problem with the summon cap is probably that it doesn't actually do what it's designed to do with a lot of spells. Since bands count as one summon, even a cap of three on menagerie or four on shadow creatures doesn't, in practice, really do anything--you don't need more than 2 harpies and a lindwurm and a manticore to kill things, for instance. And XXX's cap of eight is surely a joke.)
About (1) there would not be "no real reason" for the new proposed progressive MP cost mechanic. I gave the reasons in the OP. Perhaps they are not important enough factors. I think they are.
About (2) Different summons have different MP costs, as well as different strengths. Like Ice beasts are good against cold-blooded creatures etc. It is sometimes the case that higher level summons are strictly better than lower-level summons, but then it is not uncommon to have higher level spells completely superseding lower level spells in other schools as well.
As to moving around with an army, do people do this? I usually, at the most, keep a hound with me (it seems to have quite a long timer), and create the rest only in battle. They time out decently fast.
