Of course it's possible (assuming one has the Inquis tree).
Replies in your other thread answer that better than this necro.

(* There are some few builds where it is not possible: Most Iconics, certainly, but also some caster/Rogue builds that want a "metamagic" feat at Level 1 and need a "caster" class to qualify to do that. Note that "Arti" counts as a "caster" class for this purpose.)
This is a good approach for any build where "Skills" in general are of any value to you, to take the higher Skill-Point class first, depending whether it gets you more skills that you value. (Some multi-class builds don't value skills from every class, so it's actually a loss to go cross-class to start.)
As for the 2nd level of trapper (and when initially choosing Rogue vs. Arti), you have to balance what you gain (Rog = Evasion, Arti = Rune Arm, + trap-class Skill Points) against abilities gained by your other class(es). For example, a Wizard/Trapper may wait until 7, after Wizard 5 (for Fireball), or until 9 after Wiz 7 (for Wall of Fire), and so on.
Bottom line depends on your long-term goals: For going to 20, "What helps you level faster?" For going to 30 (including Iconic builds), "What gives the strongest L20 build going into Epics?" (Or, for HC, "What helps you stay alive better?")
