How to access variable values of an user through ssh command using sudo?

Issue

• There are two systems A and B
• On System B, there are two users : test1 and userX. Both are sudo users
• Its required to run a script from system A, which will access system B with credentials of userX and need to do sudo and run su with a single commandline option -c.
• This will be scripted which have to be run automatically without human intervention.
• The requirement is to access user test1's variables via this script. How to do that?
• Those variables not global. These variables are declared in .bash_profile as follows.

[test1@localhost ~]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
VAR=test1
export PATH VAR

• The command into the scripts are as follows.

# ssh userX@192.168.0.254 sudo su - test1 -c 'echo $VAR'

• Where System B is 192.168.0.254 and variable VAR has to print the value in it.
