travel cat macroFollow

Anyone want to write me the code for a kinda complicated macro?

If I'm in caster form or bear form, once click turns into travel form. But if I'm already in travel form, one click turns me into cat form. And if I'm already in cat form then one click casts 'dash' If 'dash' is on cooldown, it casts travel form instead.

All of these functions would be bound to one key. The basic idea is that it's my combination "yay, lets go fast from the bank to the AH" button, "crap, I ran into a mob. lets fight!" button and "OMG RUN AWAY!" button.

Possible?

I posted this in another forum and received the below as possible answers. Unfortunately, none of them work fully :/ Perhaps you can improve one.

/cast [nostance] Travel Form; [stance:1] Travel Form; [stance:3] Dash; [stance:4] Cat Form

(doesn't work if dash is on cooldown)

/cast [nostance] Travel Form; [stance:1] Travel Form; [stance:3] Cat Form
/cast Dash

(doesn't dash and kicks into caster form)

/cast [nostance] Travel Form; [stance:1] Travel Form; [stance:3] Dash; [stance:4] Cat Form
/cast [stance:3] Travel Form

(shifts well between cat and travel form, but still no dash)
