You need to give this another look. You can create a PAL AVCHD LITE 720p50 5.1 Channel for the new project dialog choices in Premiere Elements 12 using the principles that I used in my blog for doing this for 1080p. I just did it.
This should be a quick and easy procedure. Let us see what happened in your case.
In your case, the first instruction would be to copy the file name AVCHD LITE 720p50.sqpreset file found in Premiere Elements 12 Windows 7 or 8 64 bit path of:
Local Disc C
Program Files
Adobe
Adobe Premiere Elements 12
Settings
SequencePresets
PAL
AVCHD
and in the AVCHD Folder is the AVCHD LITE 720p50.sqpreset file that you copy (paste to desktop for now).
Follow the rest of the instruction in the blog post.

These following specific Notepad changes are the same whether the Notepad document reflects Premiere Elements 11 1080p or your Premiere Elements 12 720p.
<InitialNumberOfFiveOneTracks>3</InitialNumberOfFiveOneTracks>
<InitialNumberOfStereoTracks>3</InitialNumberOfStereoTracks>
Change to:
<InitialNumberOfFiveOneTracks>3</InitialNumberOfFiveOneTracks>
<InitialNumberOfStereoTracks>0</InitialNumberOfStereoTracks>
And where it says
<AudioChannelType>1</AudioChannelType>
Change to:
<AudioChannelType>2</AudioChannelType>
When the changes are made, are you placing a new file specifically named
AVCHD LITE 720p50 5.1 Channel.sqpreset in the correct Program Files location as per the path described....?
And, you can get a AVCHD.mp4 (720p50) 5.1 channel file from Publish+Share/Computer/AVCHD with the preset of MP4 HD720p50 with adjusts under the Advanced Button/Audio Tab. I just did.
I will write up the above for inclusion in my blog for 720p and obtaining a 720p 5.1 channel version of the preset.
Please review and let us know the outcome.
Thank you.
