Translation of the 'Dikaiosune' Word Group

As I have mentioned before, there is a difficulty in most English translations which tend to use two different word groups ("righteous" and "justify") to translate what is one word group in the original Greek ("dikaiosune"). This issue can lead readers in English to fail to see the connection between rightesouness and justificaiton.

A previous suggestion considered resurrecting an old English word, "rightwise", but that was never likely to be practical, I realise.

Instead, I would suggest we might base all translations around the "righteous" word group rather than the "justification" word group. This would give us the following array of terms, all related to righteousness so that the link with the single dikaiosune group in Koine Greek.

Noun – righteousness
Adjective – righteous
Adverb – righteously
Verb – to declare righteous (participle: to have declared righteous; gerund: declaring righteous) or "to be declared righteous"
Actor – the one who declares righteous
Process/Event – declaration of righteousness or declaring righteous.

This approach would result in translations such as the following (based on the ESV but with amendments as appropriate to remove the "justify" word group terminology):

Romans 3:21–28: 

(21) But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it— (22) the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction: (23) for all have sinned and fall short of the glory of God, (24) and are declared righteous by his grace as a gift, through the redemption that is in Christ Jesus, (25) whom God put forward as a propitiation by his blood, to be received by faith. This was to show the rightesouness of God, because in his divine forbearance he had passed over former sins. (26) It was to show his rightesouness at the present time, so that he might be righteous and the One who declares righteous the person who has faith in Jesus. (27) Then what becomes of our boasting? It is excluded. By what kind of law? By a law of works? No, but by the law of faith. (28) For we hold that one is declared righteous by faith apart from works of the law.
