If you want РКГ with a tilde applied (as substitute for the
not-yet-encoded multiple titlo), the character sequence is:

Р
U+FE22 COMBINING DOUBLE TILDE LEFT HALF
К
U+FE26 COMBINING CONJOINING MACRON
Г
U+FE23 COMBINING DOUBLE TILDE RIGHT HALF

Please note that while all of these characters are contained in
Unicode 6.1, the mechanism to generate a tilde spanning over three
characters is not; this extended function of the "Combining Half Mark"
characters for others than U+FE24...FE26 was only accepted recently
together with the new characters in WG2 N4078. Thus, it will be available
with the future Unicode version which will have incorporated these.

As said in my previous mail, tilde is not titlo, thus you need to
propose:
U+FE2E COMBINING DOUBLE TITLO LEFT HALF
U+FE2F COMBINING DOUBLE TITLO RIGHT HALF
and substitute the "tilde" characters in the sequence above by them.

Remark:
I have no special knowledge on Cyrillic paleography, but I remember to
have learned that the titlo may be applied to the last digit only to
mark the whole letter group as a number, thus your group can be written:

Р
К
Г
U+0483 COMBINING TITLO

Maybe I am simply in error, or a titlo spanning over more than one
letter has a significantly different meaning from the titlo being
applied to a single letter of that sequence in other contexts.
A proposal for "combining double titlo" parts shouuld address such
questions.
