Can someone help me port WebOS 3.0 from the Pre 3 to the HTC Desire Z.

Here's the similarities:
-Both on the same QSD MSM8 processors (HP is overclocked slightly)
-Both have same 512MB RAM
-Both have 800x480 displays
-Both have same display sizes (3.58" vs 3.7")
-Both have GSM + HSPA radios
-Both have physical keypads (though landscape vs portrait)
-Both have 5MP cameras with 720p capture
-Both have same battery sizes (1230 vs HTC's 1300mAh)
-Both have Wifi bgn, BT 2.1, aGPS, Accelarometre
-Both have microUSB
-Both have more similarities

I prefer the Desire Z's landscape style but really adore the WebOS 3.0
