I'd go with an archetype where you start off with one Eidolon created by the GM, with all evolutions already picked, and every few levels you can pick a new one.
For example: Tchexelthub, the winged Serpent:
1st level: Serpentine body, Flight, skilled (flight +8)
2nd level: Improved Natural Armor
3rd level: Improved natural attack (bite)
and so on.
Any evolution points gained by feats, etc., can be used to customize the eidolon, but the points gained by leveling up must be used as the GM says. The advantage is that you can call on multiple eidolons, so that if one dies, you can call upon a different one.

homebrew but this would be close pathfinder DB summoner options
Specifically
Polysummon Summoner
This archetype allows a summoner to make more than one pact with an otherworldly entity. The summoner cannot summon more than one eidelon at a time, but, they may switch out their eidelons as needed. The downside being that all the eidelons the summoner makes a pact with share a common pool of hp.
Benefit: At first level, the summoner may make a pact with one additional eidelon (two at first level). At 5th level, and each additional 5 levels (10th, 15th, 20th) the summoner gains the ability to form a pact with one additional eidelon. Note, however, that the eidelon's forms are less changeable than a normal eidelon's. The eidelons cannot be affected by the spell transmogrify.
In addition, the eidelon's all share a common HP pool (the summoner only calculates HP once for all eidelon's using the lowest CON of all his eidelons). If one eidelon is injured, then replacing it with a different eidelon results in summoning an injured eidelon. For example, a summoner (level 10) may have one quadruped eidelon with natural attacks that have fire, a serpentine that has ice natural attacks, and a biped with acid natural attacks. If the lowest CON was 12 amongst the three, the HP would be calculated for all 3 as if they had a 12 CON (although fort saves would be calculated normally for each).
To switch out an eidelon for another, the summoner may take a full round action that provokes an attack of opportunity to banish and replace an already summoned eidelon. If the summoner doesn't have an eidelon summoned, they must use the normal 1 minute long ritual to summon one first. The summoner may not use the Summon Eidelon spell to summon a 2nd eidelon while he already has an eidelon summoned. He may, however, switch out his eidelon's using a full action as specified above when the spell is already in use.
Archetypes that affect the eidelon, and only the eidelon, may be taken specifically for each individual eidelon. Thus, at first level, a polysummon summoner could have one eidelon that is normal, and one that is clockwork.
Replaces: This archetype replaces the summoners Spell Like Ability to summon monsters.
Although it might strike a different them than what you desire. Closest thing I can think of otherwise would be an old homebrew Prestige class for the binder from 3.5 the Vestige Summoner.
But that is pretty far off from your desire, so I hope the PFDB stuff helps.

Radiance House Games' Pact Magic Unbound vol. 2 has something similar for their binding classes: a summoner archetype, Spirit Caller, that binds to spirits, gains their vestigial companions, gives the companion most of the powers that would normally be granted to the summoner by the spirit, and gives the companion eidolon evolutions.
