Tiny/Large Races: Potential to Standardize or Permanently Marginalized?

[Tequila Sunrise]

Is it possible to balance Tiny and/or Large races as +0 LA, as a whole, without resorting to applying extreme and bizarre abilities/hindrances to each individual race?

In other words, what would it take to make Tiny characters generally worth playing, if they are not already? What would it take to make Large +0 LA races NOT universally appealing as tank characters? Or is it just not possible?

Both Enlarge Person and Reduce Person can be Permanencied. A Permanently Reduced Halfling/Gnome is a Tiny LA +0 character, a Permanently Enlarged Elf/Human/Dwarf/Half-orc/Half-elf is a Large LA +0 character. No funky limitations.

Arcana Evolved has giants and faen. Giants start off Medium and Faen start off Small, but after 3 racial levels Giants become Large. Faen can become Sprytes after character level 3rd, in which they become Tiny and get wings. Both are technically LA +0, but giants have to take the racial levels and faen have a level requirement to go smaller, so it does tie back to level somehow.
