See Allen & Greenough 535e on relative clauses of characteristic:
e. A Relative Clause of Characteristic may express cause or concession:—
“peccāsse mihi videor quī ā tē discesserim ” (Fam. 16.1) , I seem to myself to have done wrong because I have left you. [Causal.]
“virum simplicem quī nōs nihil cēlet ” (Or. 230) , O guileless man, who hides nothing from us! [Causal.]
“egomet quī sērō Graecās litterās attigissem, tamen complūrēs Athēnīs diēs sum commorātus ” (De Or. 1.82) , I myself, though I began Greek literature late, yet, etc. (lit. [a man] who, etc.). [Concessive.]
[*] Note 1.–In this use the relative is equivalent to cum is etc. It is often preceded by ut , utpote , or quippe :—
“nec cōnsul, ut quī id ipsum quaesīsset, moram certāminī fēcit ” (Liv. 42.7) , nor did the consul delay the fight, since he had sought that very thing (as [being one] who had sought, etc.).
“Lūcius, frāter êius, utpote quī peregrē dēpūgnārit, familiam dūcit ” (Phil. 5.30) , Lucius, his brother, leads his household, inasmuch as he is a man who has fought it out abroad.
“convīvia cum patre nōn inībat, quippe qui nē in oppidum quidem nisi perrārō venīret ” (Rosc. Am. 52) , he did not go to dinner parties with his father, since he did not even come to town except very rarely.
[*] Note 2.–The Relative of Cause or Concession is merely a variety of the Characteristic construction. The quality expressed by the Subjunctive is connected with the action of the main verb either as cause on account of which (SINCE) or as hindrance in spite of which (ALTHOUGH).

See also 537, with note:
Relative Clauses of Result are introduced by the relative pronoun quī or a relative adverb ( ubi , unde , quō , etc.). The antecedent is expressed or implied in the main clause.
The Relative in this construction is equivalent to ut with the corre sponding demonstrative: quī = ut is (etc.), ubi = ut ibi , and so on:
nam est innocentia affectiō tālis animī quae noceatnēminī; (Tusc. 3.16), for innocence is such a quality of mind as to do harm to no one.
“sunt aliae causae quaeplānē efficiant” (Top. 59) , there are other causes such as to bring to pass.
“nūlla est celeritāsquae possit cum animī celeritāte contendere ” (Tusc. 1.43) , there is no swiftness which can compare with the swiftness of the mind.
“quis nāvigāvitquī nōn sē mortis perīculō committeret” (Manil. 31) , who went to sea who did not incur the peril of death?
[] > Note 1.–Since the relative clause of Result is a development from the relative clause of Characteristic (§ 534), no sharp line can be drawn between the two constructions. In doubtful cases, it is better to attempt no distinction or to describe the clause as one of Characteristic.
[] Note 2.–Clauses of Result are often introduced by such correlative words as tam, tālis , tantus , ita , sīc, adeō . ūsque eō , which belong to the main clause.

I would suggest something like quippe quae ego filium maritum uxor uideamus . . . .
Never let an opportunity for chiasmus go to waste.
Or is it just a causal clause, using quod and a future subjunctive?
Future subjunctive?
