I have a better trick which doesn't involve cheating Flash Builder about the Flex SDK you are using. It is about patching a single bit in one compiled class. After that, the designer will open no matter the version of Flex you are using. You can read a bit more about it in my article at:

Latest Flex SDK in Adobe Flash Builder 4.6
(I've just dared to open a blog, after almost 40 years in the area!),

However, here you have the solution in a nutshell:

You have to patch the class:
com\adobe\flexbuilder\mxml\editor\MXMLEditor.class
which is inside:
eclipse\plugins\com.adobe.flexbuilder.mxml.editor_4.6.1.335153\mxml.jar

With an hexadecimal editor, open the file MXMLEditor.class and change the byte:
3D (61 dec.) at address 0x9D04
to:
AC (172 dec.)

After that, you will be able to use the Flash Builder designer with any version of Flex SDK. But be cautious and take the appropriate precautions first:

• Do a backup of the .jar file before changing anything.
• Check that the version of your mxml.jar is the same as the above.
• Revise your software license and check that it's ok for you to do the patch.
