Starting from C fret 3 on standard A string?
A .075 at A is already fairly tight at 38 pounds of tension. At C it is 54 pounds, equivalent to using a .090 for A, very tight. The .055 .040 and .028w will be at roughly 50 pounds and the .028 will probably snap due to having a thinner core.
What sort of tension are you after? Perhaps you could try detuning your current D and G strings to C and F to see how those gauges feel.
I'm actually thinking 55 40 28w/29w 18p would be very playable at about 30-20 pounds. Circle K 4 string sets only go as light as .084 .061 .043 .031 but you can order your choice of single strings.
