It is possible to roll off of the ledge and avoid the Geemers, but it is somewhat tight and the timing is likely earlier than expected.

Entrance condition:

{
  "comeInWithGMode": {
    "mode": "indirect",
    "morphed": true
  }
}

Requires:

"h_ZebesIsAwake"
{
  "or": [
    "Morph",
    "h_artificialMorphSpringBall",
    "h_artificialMorphBombThings",
    "canTrickyDodgeEnemies",
    {
      "enemyDamage": {
        "enemy": "Geemer (blue)",
        "type": "contact",
        "hits": 1
      }
    }
  ]
}

Dev note: It may be possible to come in indirect and still have enough i-frames to get through the Geemers, but Samus may be coming from a doorless room like Crateria Tube. This is not easy to model and isn't worth doing, because the player will almost certainly canTrickyDodgeEnemies enabled before enabling canArtificialMorph.
