The ultimate name... is
Blink Doug!!!
You could mostly build this guy as a Swordsage who specialized in Shadow Hand discipline. Standard-action teleport (50 ft.) at 3rd level, move-action at 9th level, swift-action at 13th level.
The Swordsage could also turn invisible, give himself sneak attack damage, etc. and he's got a d8 HD, 3/4 BAB (just like the Blink Doug), and a bunch of other cool abilities.
Here's a quick revision of Blink Doug as a sorta Rogue / Swordsage hybrid:
HD: d8 (like a Ranger)
BAB: 3/4 (like a Rogue)
Good Saves: Reflex & Will (like a Bard)

Sneak Attack, (Improved) Evasion, (Improved) Uncanny Dodge (Ex): Like a Rogue.
Supernatural Abilities (Su): DC is always 10 + 1/2 class level + Cha bonus.
Spell-Like Abilities (Sp): DC is always 10 + level of spell + Cha bonus.
Detect Teleportation (Sp):
as the power, fully augmented to your class level, at will.
Shadow Jaunt (Su): Once every 5 rounds, you can teleport yourself up to 50 ft. as a standard action. Unlike
dimension door, this does not necessarily end your turn. You can only teleport yourself, and only while carrying a light load. This is a [Teleportation] effect.
Starting at 9th level, you can up to Jaunt 100 ft. as a move action, and you can do so once every 4 rounds instead.
Starting at 14th level, you can Jaunt up to 150 ft. as a swift action, and you can do so once every 3 rounds instead.
Starting at 17th level, you can Jaunt up to 200 ft. as an immediate action, and you can do so every other round.
Note that you can, at your option, use a "slower" action if you would prefer.
Dimension Strike (Su): You can make a special attack as a standard action. You sacrifice one or more dice of Sneak Attack damage to fuel this ability. Your attack must qualify for Sneak Attack damage (i.e. you must be flanking your foe, or your foe must be denied its Dex bonus to AC), but is otherwise independent: it works even if your foe is immune to Sneak Attack damage.
Starting at 5th level, for -1d6 SA, you can ignore any miss chance due to incorporeality.
Starting at 8th level, for -2d6 SA, you can dimensionally anchor your foe (as
dimension anchor).
Starting at 11th level, for -3d6 SA, you can dismiss a summoned creature (as
dismissal).
Starting at 15th level, for -4d6 SA, you can set up a link between yourself and your target which lasts one minute. If your target attempts to use any [Teleportation] effect within that time, it must make a Will save, or be subject to the effect of the
divert teleport power.
Teleport (Sp): Once per day per three class levels, you can
greater teleport as a Sorcerer of your class level.
Plane Shift (Sp): Once per day per five class levels, you can
plane shift as a Sorcerer of your class level, except you always arrive on target.
Shadow Form (Sp): Once per day per six class levels, you can use an effect identical to the
shadow body power, as a Psion of your class level.
Astral Projection (Sp): Twice per day, you can use
astral projection as a Sorcerer of your class level.
Just my initial thoughts. I like the concept a lot! Cheers, -- N
