2 - Use the ELH rule wherein all creatures who would be affected by the time stop are allowed spell resistance against it. If they pass, they act normally along with the caster of the time stop.

4 - Perhaps add an EXP cost for casting Time Stop. If you have to lose XP to cast the spell, it becomes less attractive and will therefore be used less often.
First of all given that
time stop does not affect an area, and the ready availability of spell resistance, are you going to have all the major players on your planet carried along with the
time stop?
Elminster on the other side of Faerûn all of a sudden gets 1d4+1 rounds worth of action, because Nerf the wizard casts a
timestop spell in Kara-Tur?
I think that this suggestion is another indication of just how ill-thought out certain passages are in the ELH.
But if you decided to use SR vs
time stop, and with the feat Spell Stowaway, as a DM I'd be WANTING my players' spellcasters to cast
time stop, so I could give them a good mangling without the interference of those bothersome meatshields.
In order cast 7 time stops consecutively in a row in a single round, you need the following Epic feats:
AutoQuicken Spell I, II and III which can only be taken at 27th level or higher
Multispell x5, Minimum level 21st
So all told the caster is at least 32nd level. And has no Epic Spell Penetration, Epic Spell Focus, Improved Metamagic, or Improved Spell Capacity, in order to take better advantage of their inflated Intelligence.
In other words, the spellcaster could be casting 17th level metamagicked spells, or 16th level metamagicked spells with each metamagic feat costing one less level. Given that such a character probably would have an Intelligence of around 40 (17 +8 level +5 inherent +10 item) that means 15-16 spells memorized per day beyond the power of a 9th level spell (compared to the AutoQuicken dude who only has 7 9th level spells...)
Thus a
Septuple Empowered Time Stop (with Improved Metamagic) grants 4.5x(d4+1) rounds of extra time. Not quite the same effect, but this wizard has far more spells to burn!
