Congratulations, Sanya, on getting Masha to complement your Tanyusha! The delivery that took some months was quite a adventure but luckily the doll finally made it to your apartment. I agree with your estimate: yes, Maria is one the best dolls on the market - naive, shy, and with tender smile... one can list more virtues that, perhaps, are not a piece of cake to define.
I did not know who Lera Kudryavtseva is but read Wikipedia about her. Yes, there is an undoubted resemblance.
I would stage a scene where Tania and Maria are reading: say, one girl is busy with "Курс зоологии", the other with "Русская галерея", and they both are surrounded with countless volumes of Big Soviet Encyclopedia!
Another idea is to start manufacturing doll "Natasha" looking like Natalya Varley:
