Eagle Diagram: 5-Temperature Measurements with PT100 Sensors, MCP3424, LM334 & 0-10V Voltmeter

Hello,
I am asking colleagues to look at the eagle diagram of the system that measures 5 temperatures through PT100 sensors (in the schematic as an X3 connector) and a 2-channel 0-10V voltmeter.
First of all, I am interested in the issue of PT100. Do you have any suggestions for such a connection? Maybe you can somehow simplify the connection? The current from LM334 should be equal to 1mA. By design, the system is to be composed of elements available in the PL, therefore any hard-to-reach ready-made chips under PT100 are dropped.
Any suggestions for the layout are welcome.
Will I be able to get a 0.1st resolution in such a successful arrangement?
Thank you in advance for your response.

1. The resistance of the wires is added to the resistance of PT100, overstating the measurement result - and in this system it can not be eliminated.
2. The resolution can be even a few times better, but also without the resistance of wires the error can be about 0.5 degrees, because the temperature change by 0.1 degrees will change the voltage by 34uV, and MCP342x have a zero error to 55uV, linearity to 69uV, gain changes by 15ppm / degree and temperature change ADC will change the reading, and the current LM334 + diode can float if their temperature does not change the same.
