Mega Sensor Shield V2.4 don't work together with Yun Shield

I plan to use Mega Sensor Shield V2.4 in my the production devices. But I have a problem. Mega shield uses pin MISO, MOSI, SCK to communication with SD card. In my project pins TX0/RX0, MISO, MOSI, SCK used by the sield Yun (during programming Arduino). Even if not SD cart in socket. I must unsolder R7 and R9 then programming was going. But when insertet SD card again can't progamming.
I have 2 questions:
1. How many shields minimum I must order that you make the following changes:
a. all signals going to SD cocket (MISO, MOSI, SCK and SS) will be buffered by two SN74LVC2G126? OE signal connected to Arduino PIN PJ6 ( PCINT 15 )?
b. XBee cradles would be allocated in the following manner TX1 / dfrobot (XBee1), TX2 / RX2 (XBee2) and TX3 / RX3 (XBee3)? TX0 /RX0 is using by Yun shield when programming Arduino.
2. How long I must wait for this changes?
Best regards
