OK, here is my proposal.
The concept of this ship is described by an old joke: "The most dangerous enemy is a runner. If he is stronger, you will not run away from him; and if he is weaker, you will not catch up with him."
Indeed, very few dedicated warships can catch up with this Q-ship. The ship is disguised as a regular Subsidized Merchant, but whoever tries to attack it will be very surprised. The ship is designed to quickly get close to the target and do it up close and personal: four pop-up triple turrets with rapid-fire plasma cannons. Long range is for the weak in spirit! But wait, there's more. Electronic countermeasures, advanced sensors and software, thick armor. The Corsair, with its pathetic laser turrets, won't even scratch the paint. At the same time, the ship is within a reasonable TL14, and all systems are civilian grade (no particle beams and nuclear weapons). However, even TL14 is a serious problem for repairs in this sector (maybe that's why the Scout Service on Aramanx wants to dump this problem on us, lol). This ship can even be used for trading! With a minimum fuel supply of 1 parsec, the ship can carry 85 tons of cargo. Of course, there are collapsible tanks there, which, if necessary, will increase the range of the ship to 3 parsecs. The ship actually has Jump-2, but this capability can only be realized with drop tanks, so consider it as a Jump-1 mostly.
I didn't put a stealth coating on the ship as it would make it VERY expensive, but the ship has a small 20 ton boat, and the boat has an advanced stealth system (and advanced sensors). The boat, in turn, is also well armed and protected and can successfully fulfill the role of a heavy - but fast - fighter. The boat can also carry 8 people - not counting the pilot and gunner - for infiltration missions.
