No unless you want to list all KDE SC 4.4 binary packages in 
/etc/apt/preferences (one entry for each package, 400+ in total).

Never pin whole experimental higher than unstable.

Therefore you should tweak aptitude in such a way that the first solution 
would be the one you want.

In order to upgrade existing KDE 4.3.4 installation, something like this 
should work (untested):

# aptitude -t experimental install '?maintainer(Debian Qt/KDE 

or (a safer version):

# aptitude -o 'Aptitude::ProblemResolver::Hints::experimental=approve 
~Aexperimental' install '?maintainer(Debian Qt/KDE 

For new installations:

# aptitude -t experimental install kde-standard

or (safer version):

# aptitude -o 'Aptitude::ProblemResolver::Hints::experimental=approve 
~Aexperimental' install kde-standard/experimental

You should not run into much troube unless there are packages with 
unresolvable dependencies installed.

It has never been easy to deal with experimental because it is a dumping 
ground for lots stuff and typically only want a couple of packages.
