Practice IMC in real IMC

Hello,

I want to practice maneuvers, descending turns and basic manual
maneuvering in IMC conditions. Is it possible to get ATC to assign you
a 'practice area' in real IMC environment? Say a block of airspace
like they do for aerobatics? Of course I would first do this with a
CFII.
Previous all my maneuvering in the clouds has been during real
approaches close to the ground. All of my IFR flying is single pilot.
I have had a few cases when alone I have had to make the procedure turn
reversal and descend at the same time and I was definitely
uncomfortable with the smoothness of the descending turn. I would
focus on bank angle and descent rate and I would pass through the
bearing, or I would allow the bank rate to go beyond standard rate.
Nothing significant, 10 degrees on bearing and maybe 10 deg on bank
angle, no loss of control or serious deviations. Everything would work
out OK, but I was not comfortable and it was not acceptable performance
for me. I have since limited maneuvers in IMC to either turning, or
descending, but not both. This works well, but I know that sometime I
will get to do both again. Most of my approaches are either VOR or
NDB. ILS approaches are a piece of cake.
I can do it perfectly (well, acceptable and without error) under the
hood. I just finished a 3 hour run with a CFII under the hood and
everything was perfect. There is something different about maneuvering
in the clouds.
I know I could get a CFII in actual conditions with close to min
ceilings, and practice maneuvers during the approach, but that doesn't
sound smart to me. I don't care how good the CFII is, loss of control
in IMC at 800 feet above the ground is going to be ugly. I want to
practice with a bunch of air below me.
Of course I fly perfectly with the AP enabled

Thanks,
Greg
