Sorry - not an artist but an engineer.
Strategy for suits is to create a barrier that prevents the wearer from contacting the virus...viruses are very small (20 to 300 x 10^-9 Meters)... so the body of the suit cannot have any openings exposed to the virus any bigger. Suits are hot because they don't breathe ... no ventilation.
Some parts of the suit are a lot more likely to be exposed than others...example - arms and legs high exposure but armpits low exposure.
Idea: ventilate the suits ... small wearable backpack unit like a car vacuum with a HEPA filter on your back with a sealed connection into the suit on that exhausts through the armpits. Always creates a positive pressure inside the suit to resist infiltration of viruses
Modify small car vac to serve as protective suit ventilation source.
